Thermoelectric Properties of Cd3As2 + n mol % MnAs (n = 10, 20, 30, 44.7) at High Pressures

— The results of studying the thermal emf of composites Cd 3 As 2 + n mol % MnAs ( n = 10, 20, 30, 44.7) at high pressures up to 50 GPa are presented. In the pressure ranges of P = 28–35 GPa ( n = 10, 20), 20–35 GPa ( n = 30), and 30–35 GPa ( n = 44.7), all the materials studied exhibit specific fea...

Description
Summary:— The results of studying the thermal emf of composites Cd 3 As 2 + n mol % MnAs ( n = 10, 20, 30, 44.7) at high pressures up to 50 GPa are presented. In the pressure ranges of P = 28–35 GPa ( n = 10, 20), 20–35 GPa ( n = 30), and 30–35 GPa ( n = 44.7), all the materials studied exhibit specific features in the behavior of the thermal emf S ( P ) (extrema, inflection points on the curves or hysteresis). At a pressure exceeding 40 GPa, the thermal emf changes weakly or barely changes with an increase and a subsequent decrease in pressure.
